Author Kiese Laymon, suspended from Millsaps College for taking out a library book without permission, can assume he's been forgiven by the library community.

The Jackson, Mississippi, native, whose memoir "Heavy" was one of last year's most acclaimed works, has won the Andrew Carnegie Medal for Excellence. The award, announced Sunday, comes with a cash prize of $5,000. It is presented by the American Library Association.

"I can laugh about it now, but it took me two decades to be able to talk about it," said Laymon, who in "Heavy" writes bluntly of his troubled childhood in Mississippi.

"It was the most shameful time of my life, especially if you're a black boy in Mississippi and you're always taught that education is the way out."

Laymon received the Carnegie medal for nonfiction, and Rebecca Makkai the medal for fiction for her novel "The Great Believers," which looks back on the AIDS epidemic of the 1980s.

Makkai, a National Book Award finalist last fall, recalled spending enough time at Illinois' Lake Bluff Public Library that she could probably find the shelf with Lois Lowry's books "blindfolded."

Before getting in trouble at Mississippi's Millsaps College for failing to sign out for Stephen Crane's Civil War novel "The Red Badge of Courage" — "I did what everybody did at the time, dropped it on the floor and kicked it under the scanner," he explained — he had spent many worthwhile hours in libraries. His mother was a professor at Jackson State University and would leave him at the library while she worked.

"I've always been very, very thankful for librarians," he said. "I think the country sometimes sees them as low energy and not cutting edge, but it is something that they could look at a book like mine, which is sort of risky, and given it this award."

The Carnegie winners were announced during the library association's annual winter meeting, being held in Seattle. On Monday, the association will announce winners of the Newbery and Caldecott prizes, along with other top honors for children's literature.

The Carnegie medals were established in 2012. Previous recipients include Jennifer Egan, Colson Whitehead and Doris Kearns Goodwin. Last year's winner for nonfiction, Sherman Alexie, declined the prize amid allegations of sexual harassment.
